Chicago matches a lot of systems. My favorite is from Steve Makinen. When the majority of number of bets backed a 2023 NFL preseason team in a game with a point spread of 2.5 points or lower, that group was just 4-12 ATS (25%). Teams who play well one week usually carry over to the next. Depth matters in preseason and Chicago's backups will be motivated to make the roster on this young team.
